    Summary:

    Details: The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel through 4.2.3 does not ensure that certain slot numbers are valid, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call.
